Cylinder Relief Valves for Marine Diesel Engines

Bicera Sigma Valve Capabilities

Smaller, Lighter, More Efficient

Diesel engines are a form of internal combustion engine that ignites fuel by injecting it into the hot and high-pressure air within a combustion chamber. These engines, like all other internal combustion engines, follow a defined sequence of operations that can either be executed in four strokes or two. A stroke refers to the travel of the piston between its highest and lowest points, and each stroke is accomplished in half a revolution of the crankshaft. 

To protect against explosions, cylinder relief valves are installed in marine diesel engines to relieve pressure.   

Frequently Asked Questions

What is a cylinder relief valve?  

The cylinder relief valve is engineered to reduce pressures that exceed the standard level. The valve is kept closed by a spring, and its opening pressure is determined by adjusting the thickness of the packing piece. Only a minimal amount of lift is allowed. The escaping gases are safely discharged through a designated outlet. 

What is the function of a cylinder relief valve?   

The cylinder relief valve serves as a safety mechanism to regulate or limit the pressure within a system to prevent potential hazards. If left unchecked, excessive pressure buildup can lead to process disruptions, instrument or equipment failure, or even fire.  

What makes the BICERA crankcase relief valve different?  

We were the pioneers in creating the world's first cylinder relief valve. Our valves are perfectly compatible with the mounting system of your existing equipment. Rigorous testing has shown that the BICERA valve performs better in ensuring the safety of people and property.
